Innovation Solution
A connector assembly design featuring a socket with a housing and conductive terminals, and a plug with an insulating body and plug-in terminal, utilizing a contact arm and extension arm to enhance rigidity, and an insulating block to prevent deformation and electric shock, ensuring secure and complete electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plug-in terminal is made flexible for easy insertion, then ease of operation is improved, but the terminal becomes prone to deformation and loosening
Solution Approach 1:
The plug-in terminal is designed with a two-stage structural system: the contact arm provides flexibility during insertion (dynamic phase), while the extension arm provides rigidity during connection (static phase). This dynamic-to-static transition resolves the contradiction between ease of insertion and connectivity stability.
Solution Approach 2:
The plug-in terminal is segmented into two functional parts: the contact arm (first portion) for insertion and the extension arm (second portion) for stable connection. This segmentation allows each part to optimize its properties - flexibility for insertion and rigidity for stability - thereby resolving the technical contradiction.
2Reliability
If the plug structure is made rigid to prevent deformation, then reliability is improved, but ease of insertion deteriorates
Solution Approach 1:
The plug-in terminal transitions from a flexible state during insertion to a rigid state during connection. The contact arm flexes during insertion while the extension arm maintains rigidity for stable electrical connection, resolving the contradiction between rigidity and ease of insertion.
Solution Approach 2:
By dividing the plug-in terminal into contact arm and extension arm segments with different mechanical properties, the system achieves both flexibility for insertion and rigidity for stability without compromising either requirement.
3Object-affected harmful factors
If the contact arm is extended to cover the extension portion, then protection against electric shock is improved, but device complexity increases
Solution Approach 1:
The extension arm serves multiple functions simultaneously: it provides mechanical stability for the electrical connection and acts as an insulating cover for the extension portion. This multi-functionality achieves electric shock protection without adding separate protective components, thereby avoiding increased device complexity.
Solution Approach 2:
The protective function is merged into the extension arm structure itself rather than being a separate component. The extension arm both stabilizes the electrical connection and provides insulation coverage, combining two functions into one element to avoid increasing overall structural complexity.
